Leanchoilia major, new species			10
Fig.	3.	Illustration of the holotype.
Naraoia compacta Walcott			10
Fig.	4.	(✕ 3.) An unretouched photograph of a good specimen. The appendages are only faintly shown extending beyond the carapace at the rear of the specimen. (See pl. 15, fig. 3.)

Plate 14

			PAGE
Naraoia compacta Walcott			10
Fig.	1.	(✕ 2.) Dorsal view of a compressed and somewhat distorted specimen, on which the outline of the body trunk is well shown and, on the left side, the ends of 16 exopodites preserving their fine filaments.
	2.	(✕ 2.) Dorsal view of a specimen with the carapace shortened nearly one-half by compression. The central portion showing the hepatic glands or caeca is unusually well preserved. The posterior dorsal shield has the outlines of the fused segments and the outer border clearly indicated, and on the left side, where a piece is broken out, two of the exopodites are seen, and at the posterior margin, traces of endopodites.
	3.	(✕ 3.) Enlarged view of a specimen with peculiar features along the axis.
Leanchoilia superlata Walcott			8
Fig.	4.	(✕ 2.) Details of a separate appendage.
	5.	(✕ 2.) Another appendage of a different type.
